    Hi, we have dropped a vs motor into a vt commodore series 1. Can turn car over but cannot get it to start. Please help! Have replaced crank angle sensor. Taken to mechanics - says voltages check out ok. Getting desperate to get this car going now

    You need to link the BCM and ECU with a TECH 2. It's a security thing.

    If the BCM and ECU are still the originals, it shouldn't be a security issue, you need to change a couple of sensors over too, the engines are basically the same, just the VT uses a few different sensors. Put the VT sensors on the VS motor.

    I know the coolant temp sensor is in the VS but not in the VT, so the plug for it shouldn't be there. Don't attach anything to the VS sensor.

    The VS ecotec uses 2 seperate temp sensors on the front of the inlet manifold, ones for the temp gauge (single wire) and ones for the ECU (multi wire). The VT and later ecotecs use just the 1 single temp sensor for both ECU and temp gauge. The VS ecotec doesnt have EGR either, so you just need to swap over the inlet and exhaust manifolds from the VT engine to the VS engine, this solves the EGR and the temp sensor problems..
